Obsidian

Just started using this for a worldbuilding project, and I'm a little addicted to the Wikipedia style linking and the filepath display. Sometimes getting links to work is a little frustrating, and I don't quite understand how to use aliases correctly, but I think those are mostly me problems (or mobile problems, cause this probably works so much better and cleaner on a computer). I do want a way to quickly find empty files, cause I've left a bunch of them lying around.

LOVE THIS APP! My go-to app for anything writing related. Highly customizable, super easy to use, 1000s of community created plug-ins that allow additional functionality, tons of awesome looking (& customizable) themes... I could go on all day. I also have this on my PC and I can seamlessly sync between the two with 1 tap/click & be able to continue EXACTLY where I left off on the other device by installing a plugin. End-All-Be-All of markdown/notebook apps!

Seems decent on PC, Android app is okay but there are no widgets... For a note taking app, widgets are a big deal, at least for me. I don't like having to go to the app and go through menus and what have you, I like being able to tap a widget on my homescreen that's ready to accept and save a quick note immediately, and display recent notes' titles or whatever that I can tap on to open and read. If it's going to replace OneNote or other apps, it needs widgets.
